The entanglement is one of the key features of the quantum mechanics, that can be exploited for teleportation of quantum states. In this respect many solid state systems (e.g quantum dot) can be used quantum information processors. However, solid state modeling many-body systems is often calculation very difficult, so the approximation is used. In this work, the calculation of entanglement of ground state of many-body systems by density functional theory has been performed . For this purpose , first the charge electronic density, has been calculated than the entanglement has been investigated by the linear entropy calculation. The investigated systems is the Hooke’s atom is the system and after calculating the electric charge density of the system for different frequencies, we obtained of change entanglement system with frequency .The results indicated that with decreasing the frequency in the Hooke's atom model ,the potential was reduced and entanglement was according by also reduced.
